A little while ago BRM was invited by Top Gear Magazine to take part in a very unusual but very exciting test. It involved the Stig, the Catesby Tunnel at 2,740m long, and the BRM V16 Chassis IV, among other cars. The aim? To see whose car was the loudest! You can read the full story by clicking the link here and watching the video of the cars taking part by clicking the video link below. Who was the loudest? The BRM V16 was so loud the needle went off the scale. Image Credits : Mark Riccioni
